The concept is simple, yet potentially massive: One person, called a droplet donates $5 to the 3 for 5 Foundation. He or she then approaches three friends, educates them about the cause, and asks them to donate $5. Those three droplets go out and each find three more friends and the cycle repeats, until 20 million droplets have banded together in an effort to bring clean water to people in developing nations.

This #charitytuesday, we bring recognition to the 3 for 5 Foundation. Sign in to donate here; and don’t forget to tell 3 friends by sharing this post on Facebook and Twitter! If we each contribute just a little, we can make a huge difference.
